Yeah, I do agree that it feels a little out of place on Android, but currently I have been using it because it still feels polished and I haven't had many bugs with it. Lemmy clients in general are in their early days and many are quite rough around the edges. I've had a lot of bugs with most of them.
Connect for Lemmy has a Material You style to it and feels like at home on Android. It uses your current Material color scheme and feels a bit similar to Sync for Reddit.
Yeah I tried doing that and got the same results. I'm not sure what's going on.
